% =============================================================== The code in this package implements the Guided Image Denoising method for image denoising as described in the following paper: Jun Xu, Lei Zhang, and David Zhang External Prior Guided Internal Prior Learning for Real-World Noisy Image Denoising. IEEE Transactions on Image Processing (TIP), 2018. Please cite the paper if you are using this code in your research. Please see the file License.txt for the license governing this code. Version: 1.0 (03/28/2018), see ChangeLog.txt Contact: Jun Xu <csjunxu@comp.polyu.edu.hk/nankaimathxujun@gmail.com> % =============================================================== Note ------------ Please refer to https://github.com/csjunxu/GID_TIP2018 for the updates of the code. Overview ------------ Training Code: The code for learning external prior is provided in the folder "PG-GMM_TrainingCode", which relies on the training images in the subfolder "Kodak24" (please refer to the "Data" section). Testing Code: The function "Demo_Guided_DND2017" demonstrates real-world image denoising with the Guided Image Denoising method introduced in the paper. The function "Demo_Guided" demonstrates real-world image denoising with "ground truth" by the Guided Image Denoising method introduced in the paper. The function "Demo_Guided_NoGT" demonstrates real-world image denoising without "ground truth" by the Guided Image Denoising method introduced in the paper. Model ------------ The trained model "PGGMM_RGB_6x6_3_win15_nlsp10_delta0.001_cls33.mat" can be downloaded from https://github.com/csjunxu/GID_TIP2018/PG-GMM_TrainingCode Data ------------ Please download the data from corresponding addresses. 1. Kodak24: 24 high quality color images from Kodak PhotoCD dataset This dataset can be found at http://r0k.us/graphics/kodak/ 2. NCImages: real-world noisy images with no ''ground truth'' from "NoiseClinic" This dataset can be found at http://demo.ipol.im/demo/125/ The "CCImages" directory include two parts: 3. CC15: 15 cropped real-world noisy images from CC [1]. This dataset can be found at http://snam.ml/research/ccnoise The smaller 15 cropped images can be found on in the directory ''Real_ccnoise_denoised_part'' of https://github.com/csjunxu/MCWNNM_ICCV2017 The *real.png are noisy images; The *mean.png are "ground truth" images; The *ours.png are images denoised by CC. 4. CC60: 60 cropped (by us) real-world noisy images from CC [1]. "CC_60MeanImage" inlcudes the "ground truth" images; "CC_60NoisyImage" inlcudes the noisy images; 5. DND_2017: 1000 cropped real-world noisy images from DND [2]. Please download the dataset from https://noise.visinf.tu-darmstadt.de/ and put the files in "DND_2017" directory accordingly. 6. PolyUImages: 100 cropped images from our new dataset. The *real.JPG are noisy images; The *mean.JPG are "ground truth" images; [1] Seonghyeon Nam*, Youngbae Hwang*, Yasuyuki Matsushita, Seon Joo Kim.
